Application filed April 6, 1903. Serial No. 151,348. (No model.)

To all whom it may concern:

Be it known that I, GEORGE G. NEwooMB, a citizen of the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Ore-Oars; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention refers to improvements in orecars such as are employed inconnection with mines, quarries, and the like, and relates particularlyto dumping means for such cars.

The object in view is the production of a car capable of being dumped insuch manner as to permit the load being discharged smoothly and evenlyand without bulging or distending the sides of the car, the load beingfree to move without any binding effect, while being readily timed inits discharge.

With this and other objects in view the invention consists, incombination with a suitable truck, of a car-body movably mountedthereon,a removable gate therefor, and means for automatically removingsaid gate relative to the movement of the car-body.

It further consists, in combination with a truck, of a car-bodypivotally mounted thereon and formed with its discharge end larger intransverse section than the remainder of the body and a movabledischarge-door for such end.

It still further consists, in combination with a suitable support, of areceptacle movably mounted thereon and provided with a discharge-doorand tapering longitudinally and transversely to the lowest point of saiddoor.

It also consists in certain other novel constructions, combination, andarrangement of parts, as will be hereinafter fully described andclaimed.

, In the drawings, Figure 1 represents a view in side elevation of a carembodying the features of the present invention. Fig. 2 represents asimilar view of the same, illustrating a car in its dumping position.Fig. 3 represents a front elevation of a car. Fig. 4 represents a rearelevation of the same. Fig. 5 represents a top plane View of a truck.Fig. 6 represents a top plane view of the car-body.

In the ore-mining art, and particularly in coal-mining, it is common touse oars having their bodies pivotally mounted upon the trucks andhinged in such manner as to be capable of being dumped in almost anydirection from the truck; but in the use of such cars serious difficultyhas arisen through the fact that in discharging the load the orebindsagainst the sides of the car and causes the same to expand. Of coursethe degree of expansion at each discharge may be comparatively small;butin the course of afew months the car sides become distended or bulgedquite perceptibly and sometimes even to a number of inches, making thedumping more difficult and slow, besides shortening the life of the car.To overcome this difficulty and to facilitate the discharge of ore froman orecar, I contemplate employing, as seen in the accompanyingdrawings, a common form of truck 1, upon which is mounted a turn-table2, to which table is secured a car-body 3 by means of suitable hinges 4,whereby said body iscapable of being pivoted in a horizontal plane andtilted vertically in any desired direction. As will be observed from acareful examination of Figs. 3, 4t, and 6 of the drawings, the body 3 iswider at its discharge or front end than at its rear end and the same iswider at the base of the rear end than at the top thereof, whereby saidbody flares side Webs or brackets 6 6, extending along the.

sides of the body 3, inclosing the same and being pivoted thereto, as at7 7. Fixed to the table 2 and extending laterally therefrom are suitablearms or brackets 8 8, provided with eyes 9 9, to which are pivotallyconnected links 10 10, said links extending upwardly and pivotallyengaging the webs 6 6, as at 11, the pivot-point 11 being spacedsomewhat forwardly of the pivot 7, whereby the gate 5 will be retainedin a vertical plane regardless of the position of the body 3.

Any suitable latch device 12 may be employed for normally locking thebody 3 in its horizontal position.

In operation the car is dumped by first tripping the latch 12 and thentilting the body 3 upon its hinges 4:. By this movement of the bodythegate 5 is caused to swing upon its pivot 7, the link 10 moving with thelongitudinal movement of the body 3, but limiting the said gate 5against vertical movement, whereby the said gate is caused to assume aposition above the discharge end of the carbody. The tilting of thecar-body 3 may be done gradually, and gate 5 will open in timed relation.to the movement of the car-body, whereby the load may be discharged atany desired speed, and owing to the particular shape of the car-bodywill be free from the danger of binding and injuring the walls of thecar.

It will be observed that the particular wedge shape of the body is suchas will permit of the ready discharge of contained material even thoughthe walls of such body be slightly bulged or distended. In the loadingof cars of the type above described it is common to fill the same fromreceptacles discharged above the car, and the impact of the discharge isliable to expand the side walls of the body;

but with my construction, even though the.

walls are slightly expanded, the load may be easily and readily dumped.

Although I have specifically set forth the details of one embodiment ofthe present invention, yet it will be understood that many slightalterations may be made without depart-ing in the least from the spiritand scope of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a mechanism of the class described, the combination with arotatably-mounted support of a car-body pivoted thereto formed with adischarge opening, a gate closing said opening, Webs formed on said gateinclosing a portion of said body and pivotally engaging the same, andalink connectingsaid rotatably-mounted support with one of said webs.

2. In a mechanism of the class described, the combination with asupport, of a receptacle pivotally mounted thereon and formed with adischarge-opening, the walls of said receptacle flaring from all pointsto the point of discharge.

3. In a mechanism of the class described, the combination with asupport, of a receptacle pivotally mounted thereon having an open, frontend, the side walls of said receptacle flaring from the rear end thereofto the front end and from the upper edge of the receptacle to thebottom.

4. In a mechanism of the class described, the combination with asupport, of a receptacle movably mounted thereon and formed with adischarge-opening, thewalls of said receptacle tapering in alldirections away from the point of the discharge-opening.

5. In a device of the class described, the combination with a truck of aturn-table mounted thereon, brackets fixed to said turntable andextending laterally beyond the same, a receptacle pivoted to saidturn-table and adapted to swing vertically between said brackets, amovably-mounted gate closing one end of said receptacle, and supportscarried by the free ends of said brackets engaging said gate.

6. In a mechanism of the class described, the combination with arotatably-mounted support of a receptacle pivota lly carried thereby, agate closing one end of said receptacle and. provided with meanspivotally engaging the receptacle, and supports carried by saidrotatably-mounted support and engaging said gate for retaining the sameagainst vertical movement.
